Introduction

Ameloblastoma is a rare, benign neoplasm of odontogenic epithelium described for the first time by Broca (1868) as adamtinoma, and then re-coined by Churchill (1934). Ameloblastoma accounts for about 1% of all tumors of the jaw mainly encountered during three to five decades of life. Histologically, it is of six types- follicular, plexiform, granular, basal, desmoplastic and acanthomatous. This report illustrates a rare case of acanthomatous ameloblastoma associated with unerupted lateral incisor in the maxillary anterior region of a 13-year-old female child.
